Electric cars have been heralded as environmentally friendly, but findings from University of Tennessee, Knoxville , researchers show that electric cars in China have an overall impact on pollution that could be more harmful to health than gasoline vehicles.

A Stanford University research team has designed a high-efficiency charging system that uses magnetic fields to wirelessly transmit large electric currents between metal coils placed several feet apart. The long-term goal of the research is to develop an all-electric highway that wirelessly charges cars and trucks as they cruise down the road.
